- go环境同步一下，我在mac和ubuntu上安装的最开始使用的是go1.16，俩个系统安装都执行micro都不成功
panic: qtls.ConnectionState not compatible with tls.ConnectionState goroutine 1 [running]
记录大家估计都大同小异，后边自己在网上查了一下解决的办法因人而异，没有一个通用且行之有效的办法，如果debug过应该知道,发现 tls.ConnectionState 在是标准包 crypto/tls，也就是说，高版本的 Go 标准库的定义，和 github.com/marten-seemann/qtls 不兼容,除非公司业务必须使用这个版本，要不然请大家不要自己去给自己找事情，有个人挑战意愿的也可以试试，我这后边自己俩个系统都是用的是go1.14版本，依次执行下边的命名，有想试其他版本的也可以试试
下边正式开始：

复制代码 $ micro --help # 命令安装完在GOPATH/bin目录下，输出一下信息表示安装成功
NAME:
micro - A microservice runtime
Use `micro [command] --help` to see command specific help.
USAGE:
micro [global options] command [command options] [arguments...]
VERSION:
latest
COMMANDS:
server Run the micro server
new Create a service template
env Get/set micro cli environment
login Login using a token
run Run a service: micro run [source]
复制代码# 首先进入到项目目录，这里我以我自己的go项目目录为例
cd xxx
# 调用micro生成代码，这里不详细讲解micro的使用，大家下来仔细研究一下，先使用一下
# 默认情况下Micro生成的代码会放到GOPATH/src中，通过配置--gopath=false可以选择在当前目录下
micro new --gopath=false hello

download protoc zip packages (protoc-$VERSION-$PLATFORM.zip) and install:
visit https://github.com/protocolbuffers/protobuf/releases
// 前面的跳过，看下面的，要求我们安装一些东西，别犹豫，安装就好，后面就知道是干什么的了
download protobuf for micro:
go get -u github.com/golang/protobuf/proto
go get -u github.com/golang/protobuf/protoc-gen-go
go get github.com/micro/micro/v2/cmd/protoc-gen-micro
compile the proto file hello.proto:
cd hello
make proto
复制代码生成下面的工具：
micro protoc-gen-go protoc-gen-micro
我们还需要一个proto文件的解析工具：protobuf,可以直接去github或者codeChina下载二进制版，也可以自己编译生成protoc，我自己在codeChina上下载的zip版，解压后放到GOPATH/bin ，很明显刚才的输出是给我们生成了一个名叫hello的项目，我们cd hello,然后执行
make proto // 这个执行后法相一个错误，不要慌，输出很明显的提示了我们俩个选项：在.proto文件中添加go_packege选项，或者命令行参数中指定M这个参数，那我们去修改.proto文件，看看proto文件的格式和语法，
protoc --proto_path=. --micro_out=Mproto/imports/api.proto=github.com/micro/go-micro/v2/api/proto:. --go_out=Mproto/imports/api.proto=github.com/micro/go-micro/v2/api/proto:. proto/hello/hello.proto
protoc-gen-go: unable to determine Go import path for "proto/hello/hello.proto"
Please specify either:
• a "go_package" option in the .proto source file, or
• a "M" argument on the command line.
See https://developers.google.com/protocol-buffers/docs/reference/go-generated#package for more information.
--go_out: protoc-gen-go: Plugin failed with status code 1.
make: *** [proto] Error 1
复制代码 因为我们在项目中，所以只需要指定到项目下文件的包路径：路径使用
proto/hello，现在添加完保存好，使用protoc --proto_path=. --micro_out=. --go_out=. proto/hello/hello.proto 注意,其中的--go_out和--micro_out参数指定了生成文件的输出路径，应与上一步我们修改的go_package保持一致，
// proto 语法和编译下来可以熟悉一下，现在我们执行下面的命令看看，
protoc --proto_path=. --micro_out=. --go_out=. proto/hello/hello.proto
//对比之前的文件是不是在proto/hello的文件下多生成了俩个go文件，是的这就是使用proto文件的好处，可以生成c++、java、python等相关的文件

你可以在另一个命令行窗口执行micro list services命令，可以看到我们的服务go.micro.service.hello已经被注册：
> micro list services
go.micro.service.hello
micro.http.broker
复制代码完结：micro安装的时候看版本匹配了后面的比较简单，不过需要熟悉的东西比较多：grpc、makefile、proto、protoc，下篇会写一个通信的client
